Designing and evaluating a guiding and positioning system for indoor navigation

Mobile devices such as smart phones have gained their popularity for the purpose of information acquisition in recent years. In order to provide users with the information in indoor environments, several indoor mobile guiding systems have been developed. Most of the systems focus on how to offer qualified indoor navigation services, mainly based on geographical data and analyses. However, only having a navigation service seems to be insufficient and inefficient. Thus applications aimed at providing comprehensive information for visitors in indoor environments are needed. In this paper, we describe the design and implementation of an indoor guiding and positioning system, which not only enables a navigation service but also provides multiple types of information automatically about the indoor environments when users enter an area of the environment. Furthermore, an iPhone application, InSchool, is developed to evaluate the performance of this designed system and the test results indicate significant enhancement to positional accuracy of the application.
